TopoJSON fails with Polygon/MultiPolygon objects

[lazka]

Describe the bug

I got a topojson file and want to draw it with folium. This failed with:

  File ".../lib/python3.11/site-packages/folium/features.py", line 981, in style_data
    geometries = recursive_get(self.data, self.object_path.split("."))[
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
KeyError: 'geometries'

def fixup_topo_json_for_folium(topo_json: dict):
    # Folium only supports TopoJSON with GeometryCollection, so hack it together
    for key in topo_json["objects"].keys():
        orig = topo_json["objects"][key]
        new = {"type": "GeometryCollection", "geometries": [orig]}
        topo_json["objects"][key] = new

import folium
map = folium.Map()
# fixup_topo_json_for_folium(topo_json)
folium.TopoJson(topo_json, "objects.A").add_to(map)
map.save("bug.html")

Expected behavior

It draws the topojson

Environment (please complete the following information):

• Browser [e.g. chrome, firefox]: Firefox
• Jupyter Notebook or html files? html
• Python version (check it with import sys; print(sys.version_info)) 3.11
• folium version (check it with import folium; print(folium.__version__)) 0.14.0
• branca version (check it with import branca; print(branca.__version__)) 0.6.0

Additional context

It looks like it only supports GeometryCollection and not any of the other types, I've included my current workaround in the reproducer called fixup_topo_json_for_folium() which makes it work by wrapping all objects in a dummy GeometryCollection.
